Spontaneous bremsstrahlung during electron scattering on the nucleus in the field of a light wave has been studied for a long time (see, for example,[1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}, [22]}, [23]}, [24]}, [25]}, [26]}, [27]}, [28]}, [29]}, [30]}, [31]}, [32]}, [33]}, [34]}, [35]}). At the same time, Oleinik resonances were studied in [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}, [22]}, [23]}, [24]}, [25]}, [26]}, [27]}, [28]}, [29]}, [30]}, [33]}, [34]}, [35]}. In recent articles [24]}, [25]}, [26]}, the process of spontaneous emission of ultrarelativistic electrons on nuclei in the field of a weak electromagnetic wave was considered.
